An unopened booster box of the first edition of the Pokemon TCG has sold for $56,000 plus buyer’s premium in an auction by Huggins & Scott Auctions that closed on August 10. The unopened box, in “pristine condition” had been in the possession of one person since its acquisition on release in 1999.

This appears to be the range for this item; a sale for $54,200 was reported last year, according to Kotaku.

The price of the unopened box reflects the potential value of cards inside. A single card from this edition in perfect condition has sold for as much as $55,650, according to Beckett.
